所以,这是我得到的logcat信息.应用程序仍然可以运行,但我想知道我收到此错误的原因.我不明白为什么我这样,所以我甚至不知道该怎么问.

我很遗憾忘记粘贴主要活动.

第27行是

public class MainActivity extends AppCompatActivity  {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

super.onCreate(savedInstanceState); 是第27行.

很抱歉回答这个老问题，但我在我的项目中解决了这个异常。

我认为导致异常的原因是我们在创建活动时使用了活动的上下文。

我的代码类似于\xef\xbc\x9a

@Override\n    protected void onCreate(Bundle savedInstanceState) {\n        super.onCreate(savedInstanceState);\n        setContentView(R.layout.main);\n        regToWx();\n}\n\n\nprivate void regToWx(){\n    IWXAPI  api;\n    api = WXAPIFactory.createWXAPI(this, Constants.WX_APP_ID, true);\n    api.registerApp(Constants.WX_APP_ID);\n    String text = "123";\n    WXTextObject textObj = new WXTextObject();\n    textObj.text = text;\n\n    WXMediaMessage msg = new WXMediaMessage();\n    msg.mediaObject = textObj;\n    msg.description = text;\n\n    SendMessageToWX.Req req = new SendMessageToWX.Req();\n    req.scene = SendMessageToWX.Req.WXSceneSession;\n    req.transaction = String.valueOf(System.currentTimeMillis());\n    req.message = msg;\n\n    api.sendReq(req);\n}\n

由于该regToWx方法需要创建上下文this，但我认为上下文不能在内部使用（在某些方面）onCreate方法内部使用。所以我只是把它放在一个线程中，然后问题就解决了。

\n\n

    @Override\n    protected void onCreate(Bundle savedInstanceState) {\n        super.onCreate(savedInstanceState);\n        setContentView(R.layout.main);\n        new Thread(new Runnable() {\n        @Override\n        public void run() {\n\n            regToWx();\n        }\n    }).start();\n\n}\n

所以试着找出你用你的contextin做了什么onCreate方法做了什么，将这些代码从 it 中取出，或者只是使代码异步。
